R13 is required to mop up any/all changes and updates since R12. If you have genuine data errors or omissions then there should be no problem with inserting them in for R13 and I would personally interpret that to include backdated new starts (assuming you can justify why you did not input them at the time).

Well at least i know its not ‘operator error’ on my behalf! I couldn’t see any message saying it was down for ‘X’ period of time, and as R2 is already open i couldn’t see why R13 was ‘not working/on hold’?
